Patent abstract
The invention relates to an impedance matching circuit including: an input terminal for receiving an input signal; a variable impedance unit, coupled to the input terminal, having an equivalent impedance for providing the input terminal with an input impedance; a signal quality evaluating unit, coupled to the input terminal, for evaluating a signal quality of the input signal; and a control unit coupled to the variable impedance unit and the signal quality evaluating unit, for outputting a target control signal according to an evaluating result of the signal quality evaluating unit to adjust the equivalent impedance of the variable impedance unit.
